Silverpop Systems is the company that found its servers compromised two weeks ago, with private records of both McDonalds and DeviantArt customers and 105 other companies stolen.

Names, login names, e-mail addresses and vehicle identification numbers where stolen from Honda with another list containing three million email addresses of Acura owners also being copied.

Customers have been warned to be on the lookout for phishing attacks as a result of the breach – with it likely that the details will have been sold on to spammers or phishing companies that will use personalised emails containing vehicle registration numbers and addresses to trick additional information from the account holders.
